compression

Picked two new engInes up over the weekend. HS50 and a yet to be id'ed Craftsman Tecumseh. Both have great sounding compression and shock my hand good. ,, Also found this cool Kutchmans shroud. Definitely throwing this on something as is. Pretty popular local minibike store. I'm...

Was gonna restore this motor but I have 2 right now. No tank and has a diaphragm carb. Carb probably needs to be gone through. Has good spark and compression. No exhaust. Asking $225 plus shipping. I'll post some pictures in a little bit.

what you see is what u get, I bought it with some other mini stuff at auction, has compression, side cover broke 100 OBO TRADE PLUS SHIPPING

Noob question but does a aftermarket cam add compression ? Approx how much ? what kind of rpm does a cam add ? I'm debating on a cam 2000- 5500 or a cam for 7500 rpm .. 7500 needs 10:1 or more .. so questions are how to add rpm along with compression to satisfy the build ...

Hi ya fellas, I dont post here much anymore, but I decided to get my little drag bike out and work on the engine. It had very weak compression and was hard to start last fall so I decided to investigate the reason why. I started with checking out the valve lash. I had none..... The valves were...

got an old west bend 510, believe its 1959, very similar to 580, good compression, needs plug wire 150 plus ship

okay so i bought a new honda clone engine i broke it in changed the oil etc then i went and removed the governer and changed the valve springs aswell as a new header, while doing this i broke the gasket on the sidecover and unfortunately lost a dowel pin aswell. i havent done the valve lash...

Any way of telling about how much the compression ratio is by running a compression test on engine after you do all your mods ?

Does anyone have any YFM80 top end parts laying around? This is the little quad that I picked up for the granddaughter a few years ago. I pulled it out, fixed the flat tire, and got it running. Was just putting around and she stalled out. After pulling the head due to no compression, I found...

What kind of cam has a silver or chrome compression release

Hey guys sorry for making son any threads but I thought this will help a lot if your looking for compression http://www.prokartengineparts.com/downloads/Compression_Ratio_Guide_GX200.pdf

So if I bump the compression with a thin copper head gasket do I have to advance the timing I search OldMiniBikes I have a billet 3 hp flywheel I read it bumps 6 degrees without doing anything is it true?. Do I have to advance more? Thank you

I'm on the hunt for compression springs used in shocks/suspensions on these old minis. Taking a very rusted from end apart with heat, I unsprung the springs. I also want to play around a bit and make a front end more usuable for my weight and the design of the front end. Looking at OAL...

How do you Compression test a small engine ? Briggs OR Tec How do you do it right? With decompressors and other factors..... Ex; 5hp should have ? Briggs = 35psi Tec = 40 psi Ex; 6hp should have ? Ex; 8hp should have ? Ex; 10hp should have ? Educate me, Please

Hi guys, I have a briggs intek 206 with .060" shaved off and it is pretty hard to pull start. The cam does have the compression relief mechanism but I have not figured out the sweet spot when starting. Is there something that I'm missing? Or is it normal for it to be very hard (lift bike off...

I'm looking for a little more performance from my stock 3hp Briggs flathead. I want to keep the governor, don't plan to turn > 5000 rpms. I know raising compression too much can defeat hp at higher rpms, but what about at lower rpms? I would be happy to trade more torque at low rpms for...

i have gx200 clone with 14cc head that suppose to raise the compression to 10.5 with stock piston, i have a flat top piston in shelf so what would the compression rate then be?

Ok still a newb when it comes to engines. My boys Baja heat needed a new crankcase gasket. So today it came. 1st install didn't pay attention to lining gear markings up and way to much finger breaking compression. 2nd install looked everywhere between here and youtube. Slid gear back in and...

Hi All, I have a Baja MB200 with a 6.5hp gx200 clone. I recently added a billet rod, billet flywheel, upgraded cam, 18lb springs and chrome moly pushrods. I got the longer rod to increase compression and everything was running great. Great compression. Then I decided to put in a flat top piston...

I got an I/C Gold 5hp briggs on a pressure washer for 15 dollars at the end of a guys driveway. It has very low hours on it. But i want more compression. It seems to be the compression release that is dropping the PSI. Can i have the head shaved? How much can i have it shaved? Is there any more...
